Honeywell is expanding its building automation solutions with a Linux-based controller. Honeywell commissioned the Mainz-based software house SYSGO to create the system software for the new member of the EXCEL 5000 OPEN family. The core of the hardware platform is based on a PowerPC CPU from Motorola, for which SYSGO developed the board support package, the drivers for the required peripherals and a boot loader. The application software is created in-house by Honeywell.
